Would it be at all possible to write a stack that would "export" another 
stack to some textual format, and then another which would "import" it 
again (i.e. into a new clean stack)?

I know the general problem is hard - but I also know that my own stacks 
tend to follow certain patterns (combination of me getting in a rut, and 
the fact that I only know about 10% of what Rev can do), so it *might* 
be feasible to write such a tool that would work for my stacks.

You probably wouldn't want to write a *product* to do that - but you 
might be able to write *tool* to do it.
